imultaneous carotid endarterectomy and

S

ome patients with
coronary artery disease
are diagnosed as having
additional carotid arterydisease. This subset of patients has
been identified as a high-risk group
for cardiac and cerebral complications
following surgical intervention.
The incidence of significant carotid
artery disease in patients undergoing
CABG varies from 8-14% and coronary
artery disease is present in more than
40% of patients who meet the
indications for carotid endarterectomy.
Combined procedures steadily
increased since Bernhardt andcolleagues initial report of 16 such
cases in 19721.This combined surgery
when done awake under High Thoracic
Epidural Anesthesia (HTEA) offers an
absolute neurological monitoring & fast
tracking. Presently there are no reports
of awake combined carotid
endarterectomy (CEA) with Offpump
CABG (OPCAB) under HTEA as the
sole anesthetic.
At Wockhardt Hospitals Bangalore
from Jan 2006 to Jan 2007 we have
performed combined CEA-OPCAB in
10 patients. Age varied from 65yrs to
CCA Vein patch

74yrs. There were 3 females & 7 males.
Four patients had symptoms of TIA and
one off them had a cerebral infarct on
CT brain. All patients underwent a
carotid MRI to access the nature &
extent of block. Those who had more
than 90% stenosis with no symptoms
& symptomatic patients underwent
CEA with OPCAB. All required triple
vessel bypass. All underwent CAE
with OPCAB under high Thoracic
Epidural Anesthesia, which is the best
monitor for brain function during
carotid endarterectomy. We have
already reported 520 awake cardiac
surgeries done under HTEA as sole
anesthetic7, 8. Hence the anesthesia
protocols have been well
standardised.
RESULT
None of these patients had any
neurological events or mortality. One
female patient needed a rexploration
of the neck wound for hematoma.
There were no perioperative
myocardial infarctions. Average
hospital stay was 6 days. All patients
remained in the ICU for one day.
There were no major wound infections.
DISCUSSION
Combined procedures steadily
increased since Bernhardt and
colleagues initial report of 16 such
cases in 19721. The incidence of CVA
in patients undergoing combined CEA-CABG surgery is equivalent to those
with asymptomatic patients
undergoing isolated CABG, but much

lower than that of patients with
symptomatic carotid stenosis
undergoing isolated CABG surgery.
Combined CEA-CABG surgery shouldbe reserved for those patients who
have symptomatic or asymptomatic
severe carotid artery stenosis and
require coronary revascularisation2.
There continues to be a dilemma
regarding the best means ofsurgical
management of significant carotid
artery disease in patients requiring
coronary artery bypass surgery.
A combined approach of coronary
artery bypass and carotid
endarterectomy
has shown goodresults in patients with concomitant
carotidand coronary artery disease and
off pump techniques3.
The incidence of significant carotid
artery disease in patients undergoing
CABG varies from 8-14% and coronary
artery disease is present in more
than 40% of patients who meet
the indications for carotid
endarterectomy4. Kallikazaros et al.
found that the frequency of significant
carotid artery disease increased from5% in patients with 1- vessel disease
to 25% in 3-vessel disease and
reached 40% in patients with left main
stem stenosis5. Pre-operative stroke
risk is considered to be less than 2%
when carotid stenosis are below 50%,
10% when stenosis are 5080% and
1119% in patients with stenosis over
80%. Patients with untreated bilateral
high-grade stenosis and/ or occlusions
have a 20% chance of stroke. Thus,
the American College of Cardiology(ACC) and the American Heart
Association (AHA) guidelines for
CABG recommend carotid

endarterectomy in asymptomatic
patients with severe carotid
artery disease6.
Neurological monitoring is an
important part of safe CEA.
The various methods of monitoring
are electroencephalography (EEG),
somatosensory-evoked potential
(SSEP), transcranial doppler (TCD),
ICA stump pressure, regional cerebral
O2 saturation (rSO2), bispectral index
(BIS) and serial neurologic
assessments during regional
anesthesia. Detection of cerebral
hypo-perfusion by any of these
methods will guide for immediate
placement of intra-luminal shunt. BIS
is a single number that incorporates
information of EEG power and frequency, and also includes
information regarding activation, burst
suppression, and bicoherence. It can
provide more information regarding
interactions between cortical and sub-
cortical neuronal generators.
BIS correlates with clinical measures
of hypnosis, sedation, reduced
cerebral metabolic rate, and also
cerebral hypo-perfusion.
The best possible monitoring of the
brain would be the patient, where heis conscious, responds to commands,
there by moving his arms and legs at
command, or he would become
restless due to hypo-perfusion of brain
or would develop weakness of contra-
lateral side when a shunt could be
placed immediately only to observe
full recovery of motor power, which
are the added benefits of awake CEA
and OPCAB. None of our patients had
a stroke during immediate
postoperative period or during follow
up. There was no mortality or
morbidity due to the procedure.
CONCLUSION
Combined procedure does not add any
significant extra risk on mortality or
morbidity as compared to stage
procedure and is cost effective. The
same when done under Continuous
High Thoracic Epidural Analgesia
(Awake) offers absolute neurological
monitoring and aids fast tracking.This is worlds initial experience of
awake off pump CABG combined with
Carotid endarterectomy.

CASE REPORT
Mr J presented to the casuality with
the history of acute onset blurring of
vision in left eye followed by
unresponsiveness of 45 minutes
duration. He was a known
hypertensive on regular treatment.
There were no previous episodes of
IHD/ Stroke/ TIA. BP was150/90 mmHg and other vital parameters were
stable. He was drowsy and was noted
to have paucity of movements of right
upper limb and lower limb. In addition,
left gaze preference was present along
with equivocal plantar response. CT
scan of head which was done within
an hour of the ictus was normal. GRBS
was 142 mg %. ECG, platelet count
and coagulation parameters were
within normal limits. The risks, benefits
and cost of thrombolysis therapy with
rtPA (recombinant tissue plasminogen
activator) were explained to the family
members.
After obtaining the informed consent
of the family, rtPA was administered
intravenously at a dosage of 0.9 mg/
kg body weight, 10% of the total
dosage was given as a bolus and
remaining as an infusion over one
hour. We were able to accomplish this
within two hours of ictus MRI of brain
done within six hours of ictus revealedleft middle cerebral artery (mca)
territory stroke with a tiny speck of
hemorrhage. There was no
deterioration in the neurological status
at this point of time. Anti platelet
agents and citicholine were introduced
24 hours after the thrombolysis. CT
scan of head was repeated on fourth
day revealing mild mass effect. It was
treated with antioedema measures.
Patient improved gradually and was
conscious by fifth of ictus. He was
shifted to the ward after a stay of eight
days in MICU. He regained
comprehension for simple verbal
commands and power of hemiplegic
limbs improved to grade 3/5.
Physiotherapy and speech therapy was
continued. He was discharged after a
ten-day stay in the ward. At the time of
discharge, he was able to sit with minimal
support, walk with one persons support
and had got motor aphasia.
DISCUSSION
Thrombolysis in stroke using rtPA is an
accepted practice for certain types of
ischemic stroke. The critical part of
management of stroke is to bring the
patient within three hours of ictus for
thrombolysis (the golden period). This
window period is three hours for
intravenous thrombolysis and six hours
for intra-arterial thrombolysis. It is well
known that the benefits of thrombolysis
are apparent as reduction of disabilitythree months after the stroke.
Strict inclusion and exclusion criteria
are available (table). This case
illustrates the importance of the
Golden Hour in stroke and also the
importance of coordination between
neurologist, intensivist and emergency
room physician The Stroke Team.
CONCLUSION
1) Brain attack is as lethal anddebilitating as heart attack.
2) Awareness and education of
public and medical fraternity
regarding the need for urgency in
potential cases of thrombolysis is
important.
3) Thrombolysis with rtPA should be
used carefully by trained experts
in the field after careful
consideration in a tertiary care
centre.
4) The costs involved should be
within the reach of common man.

severely deformed Rheumatoid knee
TShe was a known case of rheumatoid
arthritis on medical treatment. She was
unable to stand or walk and had severe
pain on bending the knee.
On examination she was moderately
built but poorly nourished and anemic.
Local examination of both knees
revealed that she has wind-swipe
deformity. Right knee was in 30 varusdeformity and range of movement
was 0-90. Left knee was in 40 valgus
and further valgus till 70. Range of
movement was 0-30. Investigation:
Hb -8.2 mg %, R A factor - positive,
CRP - positive, ESR- 89mm/hr. X-ray
of right knee showed severe varus
deformity with medical tibial condyle
defect and lateral subluxation of tibia.
Left knee - severe valgus deformity
with central tibial bone defect and
lateral patellar subluxation.
Patient was admitted and complete
pre-operative work done. The team of
Orthopaedic surgeons headed by Dr.
Sanjay Pai, Rheumatologist and
Anaesthetist got involved to give her a
comprehensive team care.
We performed total knee replacement
in staged manner. First the right knee
with varus deformity was operated
using a revision total knee
replacement implants. After five days,
the left knee with severe valgus
deformity was operated. Postoperative period was uneventful.
The patient was mobilised on the third
day with walker and was discharged
on the sixth day. On the 12th day, the
patient was able to walk without
support, able to climb stairs and do her
daily activities.
Thanks to the surgical expertise now
available in India and good hospitals to
support, these patients can get back
their normal daily life style which was
thought impossible in the past.
otal knee replacement in
Rheumatoid arthritis is a
well known systematic
inflammatory disease
wherein arthritis of synovial
joints is a major component.
This disease is common in females and
affects during third, fourth and fifth
decades of the life. Initially the disease
starts with pain and joint stiffness in
small joints of hand and later involvesbig joints like hip, knee, shoulder and
elbow. In an advanced rheumatoid
arthritis all the joints of the body are
involved.
Treatment of rheumatoid arthritis is
ideally to be done by rheumatologist.
Start with NSAIDS and later go on to
combination therapy of DMARDS
(steroids, methotrexate, leflunomide,
sulfasalazine chloroquine and oral gold
salts). An Orthopaedicians role comes
only after joint pain/ swelling anddeformity are not controlled by
medical treatment.
Indication of joint replacement in
rheumatoid arthritis.
1. Severe pain in joints
2. Inability to do daily activities
3. Progressing deformity
4. Joint stiffness
Advantages of joint replacement
1. Painless and stable joints
2. Good functional movements ofjoints
3. Improvement in quality of life
4. Better disease control after
surgery
With advent of new implants, good
operation theatres, laminar flow and
surgical expertise, it is possible to
perform joint replacements even in
severely deformed joints which was
thought impossible previously.

CASE REPORT
A 45-year old Pakistani patient
presented with progressive
weakness of both lower limbs of six
months duration. He had been
bedridden for the past two months.
He had been diagnosed to have
Thoracic Cord Compression in
Karachi five years ago for which he
underwent decompressive
laminectomy at that time. The
symptoms of lower limb weakness
reappeared after a few months for
which he was reexplored. And he
improved partially. He had five such
recurrences and had undergone
surgery five times in Pakistan. Each
time the same wound at the posterior
midline was explored. The latest MRI
showed that there was both anterior
and posterior compression at the levelof T9-T10. The spinal canal was very
narrow at that level. There was no
evidence of infiltration. He underwent
surgery in two stages in our hospital.
Stage 1:
Video-assisted thoracoscopic
corpectomy and cage fixation
The patient was positioned left lateral
under GA using a double lumen
endotracheal tube intubation.
Typically, four key holes were made,through which various instruments
are passed: one for the thoracoscope
(video camera), one for the retractor,
one for suction, and one for other
surgical instruments. Under general
anesthesia, using single lung
ventilation special thoracoscopic
corpectomy instruments were
utilised to achieve adequate bone
removal of the T9 and T10 bodies.
A 60 mm cage (Medtronics) was then
used to fixate the spine from T8 to
T11. At the end of the procedure, the
holes were typically closed with an
absorbable suture and the deflated

lung is reinflated. A chest tube was
used post-operatively for three days.
Stage 2:
Laminectomy T9, T10 and unilateral
pedicle fixation T8-T11
The posterior wound was reexplored.
It was found that the laminectomy was
inadequate. Therefore, it was
completed using drills. The dura and
the exiting nerve roots at the foramina
were freed from the scar tissue,
ligaments and bone. Pedicle screw
fixation was performed unilaterally on
the right as the pedicles on the left
side did not hold the screws properly.
Post-operatively, the patient had
reduced spasticity with some recovery
of the lower limb power.

The most important factors which
played significant role for good long
term survival in our case are-
1. Antenatal diagnosis (by
ultrasonagraphy).
2. Planning of delivery (high- risk
pregnancy).
3. Timing of surgery.

anomalies.
5. Prevention of secondary lung
injury after birth.

counselled about the nature of the
disease prior to delivery of their
newborn. The baby was delivered byelective caesarean section at 37
weeks, the birth weight was 3.8 kgs.
He was immediately transferred to

pulmonary pressures were monitored
by echocardiography during the first
week of life. The small and large bowel
which had herniated on left side of
diaphragm was repaired using a
Gortex patch by combined thoracic
and abdominal approach on day four
of age once the pulmonary pressures
dropped to normal levels (Fig 3, 4, and 5).

tablets of Atenolol 50mg,
40 tablets of Metformin and th of a
cake of Mortein Rat Killer
(Bromodiolone 0.005%w/w). He was
given a stomach wash at a nursing
Home. As his general condition
deteriorated with progressive
respiratory distress, he was intubated
and ventilated. CVC was attempted,
with repeated punctures at the nursing
home unsuccessfully. Progressive
respiratory distress followed with
bilateral worsening opacities, and hewas diagnosed to have ARDS
secondary to aspiration pneumonia,
and shifted to Wockhardt Hospitals for
further management.
On arrival in the ER, he was
hemodynamically stable. Initial
evaluation revealed reduced air entry
on the right side, multiple puncture
marks present over right
supraclavicular area, right anterior
chest wall and fullness over the right
neck with no crepitus. Patient was
drowsy, opening eyes to call and
moving all 4 limbs. Central nervous
examination was normal. Chest
radiograph revealed bilateral dense
opacities, right > left [Fig 1]. Other
investigations were normal.
Chest tube was inserted into the right
side and drained about 2.5 liters ofblood tinged fluid. Despite drainage,
chest XRay showed a large
opacification on right side with non
expansion of the lungs, and CT scan of
the thorax was done (Figure 2). CT
revealed a right loculated effusion

oxic shock syndrome is a rare
but potentially fatal toxin
mediated acute febrile
illness. Although classicallyassociated with tampon use, it is now
known that many non-menstrual
conditions are related to this syndrome.
Case fatality rates for menstrual related
STSS have ranged from 5.5% in 1980
to 1.8% in 1996. Mortality rates for
streptococcal TSS are in the range of
30-70%. Early onset of shock and
multi-organ failure contribute to the
high morbidity and mortality
associated with this condition. The
condition can mimic several common
diseases. Hence, patients with fever
and rash and a toxic condition out of
proportion to local findings should have
the diagnosis of toxic shock syndrome
in their differential diagnosis.
CASE REPORT
A 26-year-old female, who had
undergone LSCS 40 days ago,
presented to us with h/o fever of seven
days and rash of five days duration. She
had a high-grade fever, not associated
with chills and rigors. The rash, which
developed two days after the onset of
fever, began on the face and progressed
to involve the palms and the soles. One
day prior to admission, the patient had
developed sore throat and loose stools.
The caeserian section wound appearedto be healing except for an area of
induration in the central portion. She
had no prior h/o fever with rash and no
other prior medical or surgical illnesses.
On examination, a generalised macular
erythrodermal rash was noted which
also involved the palms, soles and oral
mucosa. She had mild puffiness of the
face with fine scaling of skin over the
malar area. Her heart rate was 90/min;
BP- 100/70 mm Hg and temperature
103 deg F. Systemic examination was
normal except for minimal induration
and discharge from the caeserian
section scar.
The total count was 5,300; Platelet
count, Renal Function Test, Liver
Function Test were normal. CRP was
positive.
With a tentative clinical diagnosis of
toxic shock syndrome, the patient was
started on IV Reflin 500 mg thrice daily,
IV Clindamycin 600mg thrice daily, on
admission. Throat C/S, Vaginal discharge
C/S and Blood C/S were negative.
However, wound discharge C/S grew
Staph. aureus resistant to Methicillin,
sensitive to Clindamycin. The
temperature, which was 103 deg F on
admission, decreased progressively
and patient was afebrile on day four.
The skin lesions began to desquamate
by day 12 of illness and the patient
was discharged in a stable state.
What you need to know about toxic
shock syndrome
Toxic shock syndrome is a toxin
mediated multisystem disease
precipitated by staphylococcus aureusor Group A streptococcus
(streptococcus pyogenes). The
condition was first described in 1978

ventilator and extubated on the next
day. He had an uneventful recovery
and was discharged 5 days later.
Presence of bilateral large hemothorax
and an extrapleural hematoma on one
side is an unusual clinical presentation.
Central Venous Catheterisation (CVC)
is otherwise a safe and uncomplicated
procedure in experienced hands. This
was a rare complication of CVC done
outside, and labeled as ARDS. This
case demonstrates that proper
diagnosis and appropriate treatment of
a complicated condition can save lives.
Admission of a patient to a centre
having the required Critical Care
expertise and adequate facilities to
treat such patients will go a long way
in saving lives.

in children. Subsequently in 1980 it
was identified in association with
tampon use.
Non-menstrual cases of TSS were
also reported in the early 80s in
association with several surgical
procedures (e.g. rhinoplasty,
augmentation mammoplasty,
liposuction, chemical peeling, nasal
packing, post partum procedures)
and medical conditions (e.g.
pneumonia, influenza, unidentified
bacteraemia, septic arthrit is,
thrombophlebitis, meningitis, pelvic
infection, endophthalmitis).
Non-menstrual conditions
predisposing to STSS include -
surgical wound infection, postpartuminfections, focal cutaneous and
subcutaneous lesions, deep
abscesses, empyema, peritonsillar
abscesses, sinusitis, and
osteomyelitis. Necrotising fascitis,
myositis, cellulitis caused by Group
A streptococci are also known to
cause TSS.
Risk factors described with STSS
include HIV infection, diabetes, cancer,
ethanol abuse, recent h/o varicella
infection, NSAID use.
STSS should be suspected in any
patient with fever, rash, hypotension
and systemic evidence of toxicity.
The CDC criteria for diagnosis of TSS
include the following:
Fever - which is the most
common presenting sign.
However patients in shock
may be hypothermic.
Rash - classically describedas a diffuse macular
erythroderma.
Desquamation - which begins
1-2 weeks after the
onset of illness and involves
the palms and soles.
Hypotension (systolic
BP twice the upper
limit of normal
Hepatic - total bilirubin,
SGOT, SGPT at least twice
the upper limit of normal
Hematological - Platelets lessthan 100,000
Central nervous system -
disorientation or alteration in
consciousness without focal
signs.
DIFFERENTIAL DIAGNOSIS
Diseases, which may be confused
with TSS, include:
Rocky Mountain SpottedFever- in which the rash is
petechial
Leptospirosis, Kawasaki
Disease - mucocutaneous
lymph nodes enlargement
Meningococcemia - in
which the rash is petechial
or purpuric
Toxic Epidermal Necrolysis
and Steven Johnson
Syndrome.
TREATMENT
Immediate treatment should be
aimed at aggressive management of
hypovolaemic shock caused by
capillary leakage and vasodilation.
Rapid infusion of large volumes of
crystalloid solutions is the mainstay
of treatment. At times 8 to 20L of fluid
over 24 hrs may be required to
maintain pressures. Placement of a
central venous line or pulmonary
arterial catheter is recommended for
haemodynamic monitoring.

Doctors use a 4 mm endoscope to
remove brain tumour through
patients nose
Bangalore, February 23, 2007: In a
unique path-breaking surgery the
neuro-surgery team at Wockhardt
Hospitals, Bangalore, performed a
pioneering technique by which a brain
tumor was removed using a 4 mm
endoscope that was guided through
the patients nasal cavity. The surgery,
which demands exceptional skill and
specialised equipment, wasconducted by Dr. D V RajaKumar, on a
40-year old lady who was diagnosed
with a brain tumour measuring 2
centimetres. While endoscopes have
been previously used for brain
surgeries related to cavities within the
brain and occasionally to remove the
tumours from the pituitary gland
through the nose, this is the first
reported case in the country where an
endoscope was used to remove a brain
tumor without open surgery.

Innovative surgery replaces
degenerated cervical disc
Latest therapy in cervical disc
replacement designed to preserve
motion and flexibility
Bangalore, March 28, 2007:
Dr. D V Rajakumar, Consultant Neuro
Surgeon at Wockhardt Hospitals Brain
& Spine care, with his team hassuccessfully performed a total disc
replacement in the cervical spine of
26-year old Gautam Kher, a software
engineer, thus opening up a new area
of treatment for patients who suffer
from Cervical Degenerative Disc
Disease (DDD). Through the new
technique, an artificial disc replaces
the degenerated disc and allows
movement at that level. The diseased
disc was replaced using a PRESTIGE
LP Cervical Disc implant, rather than
to remove it through disectomy or
bone graft.
